FIELD

The invention is generally related to the field of plumbing fixtures. Specifically, the invention is related to hinge assemblies for toilet seats and covers.

BACKGROUND

Improving the maintenance, the cleanliness and the sanitation features of conventional toilets has been the subject of many efforts to provide improved toilet seats, toilet bowls and means for connecting them. It has been found that cleaning and sanitizing is complicated by the intricacies of separate hinge-like interconnections between the pivoted seat ring and the flange of a toilet bowl, and by exposed bolt heads and bolt covers. These components typically create excessive joint lines, which, in turn, result in hard to clean grime lines. In many installations the problems are aggravated by the hinge-like interconnection of a separate seat cover mounted above the seat for independent rotation relative thereto. Access to and cleaning of the cluttered interconnections is difficult and inconvenient and maintenance in that area is often distasteful. Therefore, a need exists for an improved toilet seat mounting assembly that provides a smooth, uninterrupted cleaning surface.

SUMMARY

In one aspect, an apparatus is provided, having a toilet seat hinge assembly comprising a shroud, a base plate, a pin configured to interconnect the shroud to a toilet seat, two bolts, and two threaded nuts. In some embodiments, the shroud comprises a contoured surface and molded bolt tracks. In some embodiments, the base plate comprises a bolt entry opening and a bolt guide. In some embodiments, each bolt comprises a threaded shaft and a head, where the heads are configured to engage the bolt entry opening and the molded bolt tracks. In some embodiments, the two threaded nuts are configured to engage the threaded shafts of the two bolts. In other embodiments, the threaded nuts are elongated, and may optionally have set screws or some intentionally cross-threaded or deformed threads to lock-set the nuts to the bolts.

In some embodiment, the molded bolt tracks are configured to receive the heads of the bolts such that when a turning force is applied to the nuts engaged on the threaded shafts of the bolts, the bolt tracks prevent the bolts from turning. In other embodiments, a distance between the bolts is variable via movement of the bolts in the bolt tracks and bolt guides.

In yet other embodiments, the contoured surface of the shroud is a smoothly contoured surface that covers the heads of the bolts. The contoured surface also provides a wipable surface that may be joint-free, whereas the covering element of the fastening components includes no joint lines to eliminate potential grime lines.

In some embodiments, the apparatus further comprises two bushings configured to receive the bolts and to be received by the seat mounting holes of a toilet. In some other embodiments, the apparatus further comprises two washers configured to receive the bolts. The connecting pin of the apparatus may comprise two pins. In some embodiments, the apparatus further comprises a toilet seat assembly, wherein the pin interconnects the shroud, the toilet seat, and the toilet seat cover.

In another aspect, an apparatus is provided comprising a toilet seat hinge assembly comprising, a shroud comprising a contoured surface, a pin configured to interconnect the shroud to a toilet seat, two over-molded bolts each comprising a threaded shaft, and two elongated threaded nuts configured to engage the threaded shafts of the two bolts. In some embodiments, the bolts each comprise a head and the shroud comprises solid end sections to accommodate the over-molding of the bolt heads, such that when a turning force is applied to the elongated nuts engaged on the threaded shafts of the bolts, the over-molding prevents the bolts from turning. In other embodiments, the bolts each comprise a head and the heads are over-molded into the shroud such that the shroud and the bolts form a single, contiguous item.

In yet another aspect, a molded bushing tree provides a variety of bushing sizes to correspond to toilet seat mounting holes, which typically vary among toilet fixtures. This feature allows for an enhanced snug fit of the overall hinge/seat assembly to a wider range of toilet fixtures.

DETAILED DESCRIPTION

Referring now to the figures, exemplary embodiments of an adjustable, dynamic, bolt position, hinge apparatus for the connection of a toilet seat and cover to a toilet are described. FIG. 1 is a rear perspective view of a toilet, toilet seat cover, toilet seat ring, and hinge mechanism, according to one embodiment. The toilet seat cover 105 is shown as being connected to the toilet seat ring 110 via pins 112, 113. The pins 112, 113, in turn, are connected to a hinge mechanism 120, which includes a shroud 125, a shroud bottom plate 130, bolts 140, 141, and nuts 155, 156. The hinge mechanism 120 may also include a shroud shield 160. Each of these features is described in greater detail below by reference to FIGS. 2-8.

The hinge mechanism 120 is the connector for the toilet seat ring 110 and toilet seat cover 105 to the toilet 103. As noted above, one feature of the hinge mechanism 120 is the shroud 125. As shown by FIGS. 1, 3, and 6, the shroud 125 is a contoured surface that, when in place on the toilet 103, provides a smooth transition that reduces or eliminates grime lines typically associated with traditional style toilet seat hinges. The contoured surface may be a single, uninterrupted surface, that is also a wipable surface. As used herein, the term “wipable” refers to a surface that may be easily wiped without sharp edges or corners so that the full surface may be wiped with a cleaning cloth or sponge to remove residue. In other words, the contoured surface of the shroud 125 is a smooth surface, facilitating cleansing and sanitation, and easy wiping of the surface. Together, the shroud 125 and a shroud shield 160 provide a housing and, thus, full concealment, for the other fastening components of the hinge assembly, such as the bolts 140, 141 and their connecting surfaces. The single piece shroud 125 provides enhanced structural stability to tie hinge assembly as a whole, and may have optional internal ribbing 537 for added strength and support.

As shown in the breakaway portion of FIG. 1, the hinge mechanism 120 has a single bottom plate 130 to facilitate the concealed fastening of the hinge mechanism 120 to the toilet 103. The single bottom plate 130 has bolt guides 133, 134. In other embodiments, a hinge mechanism 520 may employ two separate bottom plates 530, 531 and bolt guides 533, 534 as shown in FIG. 5.

In some embodiments, the bottom plate 130 also includes bolt entry openings 131, 132. The bolt entry openings 131, 132 allow for a bolt head 140, 141 to be inserted through the bottom plate 130, and positioned along the bolt guides 133, 134 by sliding back and forth in the guides 133, 134. The size of the bolt guides 133, 134 are such that the head of a bolt 140, 141 is secured within the hinge mechanism 120 and is prevented from pulling out of the bolt guides 133, 134 when secured in place on the toilet 103. Alternatively, the separate bottom plates 530, 531 may have bolt entry openings at the start of the bolt guides which extend in opposite directions from the bolt entry openings. In such an alternative embodiment, the bolt entry opening is sized to accommodate entry of the head of a bolt into the shroud, and the bolt guides are sized in a manner similar to that described to facilitate retention of the bolt head in the shroud.

As shown in FIGS. 2-4 and FIG. 6, bolt tracks 170, 171 are formed into an upper inner surface of the shroud 125, and correspond in position to the bolt guides 133, 134. The bolt tracks 170, 171 are sized to accommodate the head of a bolt 140, 141, such that when a nut is turned onto the threads of a bolt 140, 141, the bolt tracks 170, 171 prevent the bolt 140, 141 from turning, providing for ease of installation. Additionally, the bolt tracks 170, 171 act as a guide for the bolt head 140, 141 as it slides into position within the bolt guides 133, 134. Additoinally, the bolt tracks 170, 171 provide increased stability to the overall assembly. The bolt tracks 170, 171 and the bolt guides 133, 134 allow the distance of the bolts 140, 141 to one another to be adjustable (i.e. dynamic), and thereby accommodate various spacings between toilet seat mounting holes in toilets. Such spacing in toilets may vary from brand to brand and even between different toilets of the same model, due to a variety of factors, including, but not limited to the fabrication of toilets and the difficulties of casting porcelain. The ability to accommodate the various spacings in toilet seat mounting holes, provides for a “universal” application of the assembly in many different toilet applications.

The bolts 140, 141 can be of a variety of configurations. The heads of the bolts 140, 141 are shown in a number of the figures to have a square head to securely engage the bolt track 170, 171 of the shroud 120. However, the shape of the head of a bolt is not necessarily limited to a square configuration. The only limitation to the head shape, is that when a nut is turned onto the threads of the bolt, the shape of the head of the bolt is configured in such a manner as to affect the engagement of the head of the bolt with the bolt track so that the bolt is prevented from turning as the nut is tightened. Thus, the shape of the head of the bolt may range from oval, to triangle, square, rectangle, pentagonal, and the like. The shape of the head may also be a circular shape with opposing sides being flattened such that when engaged in the bolt track the flattened sides prevent the bolt from turning. Optionally, the end of a bolt track may be contoured to complement the shape of the head of the bolt and aid in preventing undesired turning of the bolt when tightening a nut. The interfacing fit between the bolt head and the bolt track also adds stability to all components of the assembly.

The shaft of the bolts 140, 141 are inserted through the seat mounting holes provided in the toilet 103. The holes may optionally be lined with a bushing 145, 146, to fill void space thereby providing a tighter fit for the bolt 140, 141, and resulting in less movement of the seat ring 110 and cover 105, when in place on the toilet. Nuts 155, 156 are used on the bolts 140, 141, to secure them and the whole seat ring 110, cover 105, and hinge 120 assemblies to the toilet. As shown in FIGS. 1, 2, 6, and 7, the nuts 155, 156 may be elongated thus covering a larger section of the bolts 140, 141 than traditional nuts, although traditional nuts may be used. A washer 150, 151 may optionally be used between the nut 155, 156 and the toilet 103 to provide a tighter connection with less likelihood of loosening. In some embodiments, the washer 150, 151 may be made of a compressible material to provide an additional lock feature.

FIGS. 1, 2, and 6 show the elongated nuts 155, 156, according to one embodiment. As described, the elongated nuts 155, 156 serve several functions including, but not limited to tightening the bolts 140, 141 to secure the hinge mechanism 120 and thus the seat assembly to the toilet 103, and providing additional structural integrity to the bolts 140, 141. FIG. 7 illustrates optional mechanisms for securing the nut 755 to a bolt 140, 141 to prevent reversal of the nut 755 from the threads of the bolts 140, 141, which would then lead to loosening of the seat mechanism. According to one embodiment, a set screw 760 may be inserted through the side of the nut 755, and to seat against the threads of the bolts 140, 141. According to another embodiment, the last turn, or last several turns 771, of the threads 770 of the nut 755 may be cross-threaded, or other wise deformed, to cause a mismatch with the threads of the bolts 140, 141, thus providing a mechanism for preventing reversal of the nut 755 from the bolts 140, 141. This feature is accomplished due to the custom increased length of the nut, compared to conventional toilet seat mounting nuts. Nut length may be designed for the base of the nut to closely align with the bottom of the bolt, after taking into account industry standard thickness of toilet porcelain. To facilitate such cross-threading and/or deformation, the bolts and nuts may be made of plastic materials such as polyethylene, nylon, polypropylene, silicone, and the like, and mixtures or blends thereof.

As shown in FIG. 1, the pins 112, 113 may be separate pins, that may be inserted through passages 114, 115 in the seat ring 110 and into apertures 116, 117 (not shown in FIG. 1 due to orientation of the view) in the cover 105, and into apertures 109, 111 (111 not shown due to orientation) in the shroud 125. Alternatively, the pins 112, 113 may form a single pin, that may be inserted through the passages 114, 115 in the seat ring 110 and into the apertures 116, 117 in the cover 105, and into the apertures 109, 111 in the shroud 125, via a through hole in the cover 105 (not illustrated). The passages 114, 115 in the seat ring 110 are formed in a relief section 118 of the seat for such connection purposes.

Returning to FIG. 2, a frontal view of the hinge assembly 120 is shown. The hinge assembly 120 may have a cover shield 160 at its front to facilitate injection molding of a “hollow” or encapsulated piece, and to conceal the inside area of the shroud 125. The cover shield 160 is configured to leave an open access area 161 for the insertion of pins 112, 113. As noted above, the pins 112, 113 may be separate, as shown, or they may form a single pin. The cover shield 160 may be attached by any method known to those of skill in the art such as by gluing, snap-in connections, or heat or sonic welding, depending upon the materials used.

In another aspect, a fixed bolt position hinge apparatus is illustrated by FIGS. 8-10. FIG. 8 is a rear perspective view of a toilet, toilet seat cover, toilet seat ring, hinge, and shroud mechanism according to one embodiment. The toilet cover 805 is shown as being connected to the toilet seat ring 810 via pins 812, 813. The pins 812, 813 in turn are connected to a hinge mechanism 820, which includes a shroud 825, bolts 840, 841, and nuts 855, 856. Each of these features is described in greater detail below.

The hinge mechanism 820 is the connector for the toilet seat ring 810 and toilet seat cover 805 to the toilet 803. As noted above, one feature of the hinge mechanism 820 is the shroud 825. As shown by FIGS. 8-10, and as previously described, the shroud 825 is a single contoured surface that, when in place on the toilet, provides a smooth transition that reduces or eliminates grime lines typically associated with traditional style toilet seat hinges. The single contoured surface of the shroud 825 provides an exceptionally smooth, continuous surface, facilitating cleansing and sanitation and easy wiping of the surface. Additionally, the single shroud 825 provides structural stability to the overall hinge mechanism 820.

As shown in FIG. 9, the hinge mechanism 820 has shroud 825 with solid bottom end sections 830, 831. The solid end sections 830, 831 accommodate bolts 840, 841, which are over-molded into the hinge mechanism, within these solid end sections. The shroud 825 may optionally have, internal ribbing 837 to provide additional support and rigidity to the shroud 825 between the solid end sections.

In such embodiments, the hinge mechanism 820 includes shroud 825 with solid portions which allow for over-molding the head of the bolts 840, 841, such that the bolts become an integral part of the shroud 825. Due to over-molding, the bolt 840, 841 is prevented from turning upon engagement with and subsequent tightening of the nuts 855, 856.

The bolts 840, 841 can be of a variety of configurations. For example, the heads of the bolts 840, 841 are shown in a number of the figures to have a square head to securely over-mold into shrouds 825. However, the only limitation of shape is that the shape of the head of a bolt entail adequate surface area and configuration to provide permanent, firm over-molding to secure the bolt from turning or loosening when a nut is applied to industry standard torque force. The bolt becomes integrally molded, or over-molded, into the shroud such that the bolt and the shroud are essentially a single item with enhanced strength and rigidity, affecting the entire assembly.

The threaded shaft of the bolts 840, 841 may be inserted through the seat mounting holes provided in the toilet 803. The holes may optionally be lined with a bushing 845, 846 to fill void space thereby providing a tighter fit for the bolt 840, 841 and resulting in less movement of the seat 810 and cover 805. Nuts 855, 856 are used on the bolts 840, 841, to secure them and the seat ring 810, cover 805, and hinge 820 assemblies to the toilet. As shown in FIGS. 8 and 10, the nuts 855, 856 may be elongated thus covering a larger section of the bolts 840, 841 than traditional nuts, although traditional nuts may be used. A washer (not shown) may optionally be used between the nut 855, 856 and the toilet 803 to provide a tighter connection with less likelihood of loosening. In some embodiments, the washer may be made of a compressible material.

FIGS. 8 and 10 show the elongated nuts 855, 856, according to one embodiment. As described, the elongated nuts 855, 856 serve several functions including, but not limited to tightening the bolts 840, 841 to secure the hinge mechanism 820 and thus the seat assembly to the toilet 803, and providing additional structural integrity to the bolts 840, 841. A couple of alternative, and optional, mechanisms for securing the nut 855 to a bolt 840 to prevent reversal of the nut 855 from the threads of the bolt 840, which would then lead to loosening of the seat mechanism are described. According to one embodiment, and as previously described, a set screw may be inserted through the side of the nut, and seated against the threads of the bolt. According to another embodiment, the last turn, or several turns, of the threads of the nut may be cross-threaded, or other wise deformed, to cause a mismatch with the threads of the bolt, thus providing a mechanism for preventing reversal of the nut from the bolt. To facilitate such cross-threading and/or deformation, the bolts and nuts may be made of plastic materials such as polyethylene, nylon, polypropylene, silicone, and the like, and mixtures or blends thereof.

As shown in FIG. 8, the pins 812, 813 may be separate pins, that may be inserted through passages 814, 815 in the seat 810 and into apertures 816, 817 (817 not shown in FIG. 8 due to orientation of the view) in the cover 805, and into apertures 809, 811 (811 not shown due to orientation) in the shroud 825. Alternatively, the pins 812, 813 may form a single pin, that may be inserted through the passages 814, 815 in the seat 810 and into the apertures 816, 817 in the cover 805, and into the apertures 809, 811 in the shroud 825. The passages 814, 815 in the seat 810 are formed in a relief section 818 of the seat for such connection purposes.

Returning to FIG. 9, a bottom view of the hinge assembly 820 is shown. The hinge assembly 820 may have a cover shield 860 that is formed in the front to facilitate injection molding of a “hollow” or encapsulated piece, and to conceal the inside area of the shroud 825. The cover shield 860 is configured to leave an open access area 861 for the insertion of pins 812, 813. As noted above, the pins 812, 813 may be separate, as shown, or they may be a single pin inserted through a through-hole in the cover 805 (not illustrated). The cover shield 860 may be attached by any method known to those of skill in the art such as by gluing, snap-in connections, or heat or sonic welding, depending upon the materials used.

In another aspect, a bushing tree 1100 is provided with matched pairs of various sized bushings to accommodate the variances in seat mounting hole diameters among toilets. FIG. 11 illustrates one such molded tree. The bushings 120 may be integrally formed of single material and interconnected via the stems 1105 and branches 1110 of a single tree 1100 such that each individual bushing may be separated from the tree and used for their individual application. Narrower portions of the material may be formed at the connection of the bushing 1120 to the branch to facilitate ready removal of the bushing 1120 from the branch. The materials may be made from a variety of materials such as polyurethane, polyethylene and polypropylene. In some embodiments, the material that forms the tree and attendant bushings is a silicone material. In other embodiments, the material is a pliable, flexible, and/or compressible material such that bushings may he shaped to fit various imperfections in seat mounting holes in toilets resulting in a snug and improved seat cover, seat ring, seat hinge assembly, with less “seat wiggle.” By configuring the multiple bushings on a “tree,” a packaging advantage exists by offering them as a single item.

As noted above, the molded tree 1100 may contain bushings 1120 of various sizes and number, because seat mounting holes on toilets often vary in size. Hence, while the inner diameter of the bushing is of a constant size to match the diameter of the threaded shaft of the bolt, the outer diameter of the bushing will be varied to accommodate the varying size of seat mounting holes in toilets. This will result in bushings of varying outer diameter to allow an installer to choose the bushing most appropriate to the toilet to which the seat assembly is being attached. The number of bushing sizes on a tree is not limited.
